Ambient Hydrogenation and Deuteration of Alkenes Using a Nanostructured Ni‐Core–Shell Catalyst

A general protocol for the selective hydrogenation and deuteration of a variety alkenes is presented. Key to success these reactions use specific nickel-graphitic shell-based core–shell-structured catalyst, which conveniently prepared by impregnation subsequent calcination nickel nitrate on carbon at 450 °C under argon. Applying this nanostructured both terminal internal alkenes, are industrial commercial importance, were selectively hydrogenated deuterated ambient conditions (room temperature, using 1 bar hydrogen or deuterium), giving access corresponding alkanes deuterium-labeled in good excellent yields. The synthetic utility practicability Ni-based demonstrated gram-scale as well efficient catalyst recycling experiments.
